Control Your Power.Control Your Life.

Home backup power. Comfort. Security. Convenience.

A permanently installed Generac home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and sits outside just like a central air conditioning unit. A home backup generator delivers power directly to your home’s electrical system, backing up your entire home or just the most essential items. Now coming with FREE Mobile Link™, allowing you to monitor the status of your generator on a phone, tablet or computer from anywhere in the world. How It Works

Mobile Link™ Remote Monitoring FREE with every Guardian Series Home Standby Generator

Allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet, or PC. Easily access information, such as the current operating status and maintenance alerts. With Mobile Link, you are taken care of before the next power outage.

Automatic Operation

Don't worry about having to be there to start and turn off your Generac home backup generator because it does that automatically--whether you're home or away.

Generac created the home backup generator category. Today, our generators are preferred by most homeowners who invest in home backup power.

Power Directly to Your Home

You'll never have to run an extension cord through a window or door again. Your Generac home backup generator safely delivers power right to your home's electrical panel.

Home Backup Generators: What Do I Need to Know?

We know a home backup generator is a big investment. Here's what you need to know to make an informed decision about your Generac home backup generator purchase.

How Do I Choose the Right Generator for Me?

Generac has an online sizing calculator that can help you determine the right home backup generator for your unique needs. The best way, though, is to work with one of our 5000 dealers. They'll help you select the right generator, and provide you with a free, in-home assessment.

What's Involved in Installing a Home Backup Generator?

Installing a home backup generator is an exciting time. Your installer will prepare the installation site outside your home, place the generator, run the natural gas or LP fuel line, install the transfer switch, and make all of the necessary electrical connections. And they will make sure that your backup generator runs properly, and is ready for its first power outage.

How Much is Everything Going to Cost?

Generac home backup generators start at $1,949--the most cost-effective on the market. Installation costs vary by system size, installation considerations, and local building codes. We recommend getting a free, in-home assessment from a Generac dealer near you.
